Product Description

Since sodium lines tend to be quite narrow, DayStar Filters has built a narrow filtering system of Sodium Na-D (5895.9Å) to accommodate this of <0.5Å to isolate the lines from continuum. They are excellent for both visual and photographic purposes. The resulting image depicts high detail in granulation, supergranulation and P-modes. Sodium Na-D has low excitation when the Sun's low chromosphere is heated when loops are passing through flares. The visual and photographic images produces will show Calcium and revealing granulation but much more emphasized and visible as usual. The observer can be heated to observe the higher of the two Na D lines for doppler observation.

These filters have until now been primarily used for research purposes only, performing doppler and supergranulation studies. Narrow bandpass Na D line filters have also been used in deep-sky observations of IO, but with significantly larger apertures.
